uSwap — Anything in, anything out: Verify Payments Securely

About

uSwap lets you buy crypto with the everyday payment apps you already use, and swap across chains — right from your browser.

When you buy crypto with cash on uSwap, a peer on a decentralized order book sends you the crypto and you pay them with your usual payment app. The uSwap extension privately confirms that you sent the payment, so your crypto is released automatically — no screenshots, no manual review, and without ever sharing your login.

WHAT IT DOES
• Powers the fiat on-ramp on uSwap (app.uswap.net): finish a purchase by paying with the app you normally use.
• Confirms your payment privately: the extension reads your own payment confirmation and produces an encrypted proof. Your login, password and session data never leave your browser — only the encrypted proof is sent.
• Side panel: track and complete your on-ramp next to any page.

HOW YOUR PRIVACY IS PROTECTED
• The extension never asks for your payment passwords and never stores your credentials.
• Plaintext payment-session data never leaves the extension — only a tamper-proof, encrypted proof is relayed to complete your purchase.
• Access to a payment platform is requested only when you choose to pay with it. The install prompt never asks for access to your accounts.

WHO IT'S FOR
Anyone who wants to buy crypto with the everyday payment apps they already use — without a centralized exchange, KYC walls, or hidden fees. uSwap is 0% fee: what you see is what you get.
